Answer:
At focus.
Explanation:
When the object is placed at the focus of a concave mirror, the image will form at infinity. The formed image is real and inverted and its size is highly enlarged.
When the object is placed between the pole and the focus, the image will formed behind the mirror. The formed image is virtual and erect and its size is enlarged. This is the only case when the formed image is virtual and erect.
B. the rate of evaporation of a fluid
C. how much energy it takes to warm a fluid
D. the density of a fluid
E. a fluid's resistance to flowing
Answer:
E. a fluid's resistance to flowing
Explanation:
Viscosity, also known as "thickness" is a rheological property that describes a fluid's resistance to flowing, fluids of low viscosity, like water, flow more easily while high viscosity fluids, like mud, are harder to move through. It is an important property because it determines the energy required to make a certain fluid flow.
Answer:
5.03×10¯⁷ N
Explanation:
From the question given above, the following data were obtained:
Mass of the person (M₁) = 55 Kg
Mass of the car (M₂) = 1234 Kg
Distance apart (r) = 3 m
Gravitational constant (G) = 6.673×10¯¹¹ Nm²/Kg²
Force (F) =?
The force between the person and his car can be obtained as follow:
F = GM₁M₂ / r²
F = 6.673×10¯¹¹ × 55 × 1234 / 3²
F = 6.673×10¯¹¹ × 67870/ 9
F = 5.03×10¯⁷ N
Thus, the force between the person and his car is 5.03×10¯⁷ N
The answer is:
The track of the storm determines how much rain will fall.
The explanation:
-Storm tracks are the relatively narrow zones in seas and oceans where storms travel driven by the prevailing winds.
-hurricane is a tropical cyclone with winds of 74 miles (119 kilometers) per hour or greater that occurs especially in the western Atlantic, that is usually accompanied by rain, thunder, and lightning, and that sometimes moves into temperate latitudes. and it has aspects that can cause damage, these are flood, wind, surge, heavy rains and tornadoes.
A high pressure center is generally characterized by cool, dry weather. The movement is cause by the addition of forces due to gravity because their higher pressure compresses the column of air near the center of the area nto greater density and so greater weight compared to lower pressure, lower density and lower weight of the air outside the center.
